New kind of microstrip antenna: the monopolar wire-patch antenna

In reply to the Comment [given by Burbery, R.A., Elect., Lett., vol., p. 745, 1994] we wish to say: (i) Our antenna is a microstrip antenna with a dielectric substrate and a height varying between λ/20 and λ/100. At such heights the 'folded dipole' adaptation techniques are not applicable

A comment on the use of TE/TM polarization notation

Inconsistent use of the transverse electric (TE) and transverse magnetic (TM) polarization notation in two articles on the scattering of a plane wave from a strip grating (see K. Uchida et al., ibid., vol.AP-35, p.46-52, Jan., 1987, and J.H. Richmond, ibid., vol.AP-28, p.883-7, Nov. 1980) is discussed. It is proposed that only the more standard notations be used to refer to the different polarization cases

Authors' reply [to comments on "Effect of system imperfections on BER performance of a CDMA receiver with multipath diversity combining"]

For original paper see Panicker, J. and Kumar, S., ibid., vol.45, p.622-30 (1996). For comments see Xie, J. et al., ibid., p.1414-15. In our original paper, a direct-sequence code-division multiple-access (DS-CDMA) system with imperfections in power control, channel parameters, and spreading code-phase estimation was analyzed. Xie, J. et al. noted three errors and omissions in the paper. Our responses to each of the three cases are provided.

Who (and with whom) uses more emoji? Exploring individual,relational, and motivational characteristics driving emoji use

Emoji use, despite being pervasive in digital communication, is often dependent on individual characteristics (e.g., gender, age, personality), relational dimensions (e.g., intimacy with specific others), motives for using them (e.g., because emoji allow to better express emotions), and the context in which they are used (e.g., emoji use is considered more appropriate with closer interlocutors, such as friends). However, research has yet to examine if and how these variables associate with emoji use frequency when considered together. In a correlational study (N = 444), we explored the relative contribution of individual characteristics, perceived relatedness to others, and motives to explain the frequency of emoji use with different interlocutors. Hierarchical linear regressions showed that being younger, scoring higher on conscientiousness, and resorting to emoji for personal contact were correlates of emoji use frequency with closer interlocutors (e.g., family and friends). In contrast, being older, scoring lower on agreeableness, and perceiving more relational intimacy were correlates of emoji use frequency with more distant interlocutors (e.g., supervisors and doctors). Overall, results highlight the need to account for multiple variables at different levels to examine emoji use patterns in digital communication.     

Bound for linear complexity of BBS sequences [reply to comment]

The sequence presented in the comment [see ibid., vol. 34, p. 1057-8, 1998] is not a counterexample for the linear complexity of Blum-Blum-Shub (BBS) sequences [see Siam J. Comput., vol. 15, p. 364-83, 1986], although we agree that the proof of our proposition [see ibid., vol. 34, p. 450-1, 1998] is insufficient
